Versatile vector tools for efficient protein screening across multiple expression systems
FEBS Open Bio, EarlyView.A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

Molecular analysis of transferable tetracycline resistance plasmids from Clostridium perfringens [PDF]
, 1985 Conjugative tetracycline resistance plasmids from 15 Clostridium perfringens isolates from piggeries were analyzed by restriction endonuclease digestion and agarose gel electrophoresis. Seven isolates from one farm were found to carry a 47-kilobase pair (

FEBS Open Bio, EarlyView.The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...

Aquaporin‐3 and aquaporin‐5 impact the development of pancreatic ductal adenocarcinoma spheroids
FEBS Open Bio, EarlyView.Schematic representation of the role of aquaporin‐3 (AQP3) and aquaporin‐5 (AQP5) in pancreatic ductal adenocarcinoma (PDAC). Both proteins are upregulated in PDAC and are associated with tumor progression and metastatic potential. Silencing AQP3 or AQP5 in PDAC spheroids results in decreased diameter, area, and overall growth, underscoring their key ...

pFAR plasmids: New Eukaryotic Expression Vectors for Gene Therapy, devoid of Antibiotic Resistance Markers [PDF]
, 2008 Efficient production of eukaryotic expression vectors requires the selection of plasmid-containing bacteria. To avoid the risk of dissemination of antibiotic resistance markers, we developed a new system to produce a family of plasmids Free of Antibiotic

The plasmid-stabilizing Ytl2 protein coats DNA in a sequence-independent manner
, 2001 Plasmids carrying the ytl2 gene from the large resident plasmid pSLT of Salmonella typhimurium were stabilized >10 5-fold (compared to control ytl2-free plasmids) in S. typhimurium cells.

Directed evolution of enzymes at the crossroads of tradition and innovation
FEBS Open Bio, EarlyView.An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.
